MusicBee 用の Logitech プラグインを作成しています。私が持っている唯一の問題は、アートワークの画像、再生および一時停止の画像が読み込まれないことです。VS2012 リソース ファイル内のイメージを使用するさまざまな方法をテストしました。しかし、それらのどれも機能しません。イメージを dll ファイルにロードする必要があり、イメージは HICON または HBITMAP でなければなりません。以下は、私のプロジェクトの完全なクラスです。完全なプロジェクトはBitbucketにあります。
//This is the code I have used for loading an image.
playIcon = LoadIcon (GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_ICON1));
playIconHandle = m_lcd.AddIcon(playIcon, 16, 16);
m_lcd.SetOrigin(playIconHandle, 2, 2);
